Huh. Given that I never completed a single trade on PucaTrade when I was there (finding people who will trade from NZ is/was damn near impossible) I'd never get any points to actually get cards with now. Will check out Card Sphere

fyi, I recommend offering 75-85% for cards in your Want list on CardSphere. It seems to be the sweet spot for getting the best value and frequency of trades. If you don't get the cards you want you can try increasing your offer percent.
